方法がとられていた。 When annealing or solution annealing a thin metal plate, such as a rolled alloy steel or stainless steel plate with a thickness of 0.05 to 1 mm, conventionally a furnace with a horizontal tunnel structure in which the preheating section, heating section, and cooling section are connected is used. A method was used in which a thin metal plate was passed through this at a predetermined speed.

た。 However, with this method, the objects to be processed are extremely thin and have no stiffness, so they sag while moving through the furnace, and in order to prevent this from coming into contact with the furnace wall and uneven heating and cooling, the cross-sectional area of the furnace must be increased. No. This, combined with the fact that there is a lot of heat dissipation and atmosphere outflow from the entrance and exit, has the drawback of increasing consumption of electricity and atmospheric gas. Further, in the above method,
The method used to guide the transfer of the workpiece was to use upper and lower rolls with a layer of felt layered on the surface, sandwich the workpiece between the upper and lower rolls, and press the upper roll with a cylinder, etc. However, there were disadvantages in that the workpiece was prone to wrinkles and scratches due to localized overpressure due to curvature in the width direction of the workpiece and the attachment of minute foreign matter, and the number of good products was low.

When annealing or solution-treating a thin plate with a thickness of 0.05 to 1 mm at 10 m/min at 1000°C for 15 seconds, a predetermined amount of furnace air is supplied from the furnace air introduction box 1, and the heater 12 of the heating furnace 5 is turned on. It heats and operates the blower 22. In this way, the furnace air descends from the fore-air box through the inlet tube 4 and is dissipated from the inlet section 7, and the furnace air flows through the furnace core tube 11 of the heating furnace 5.
The gas then descends through the core pipe 14 of the gas circulation type cooling device 6 and is dissipated from the outlet section 8. After the thin plate A runs horizontally on the transfer line, its direction is changed by the feed roll 24, and it moves up the feed tube 4 into a hollow shape in countercurrent to the reactor air, and is reversed at the reactor air introduction box 1. The direction is changed again by the roll 3, flows down the furnace core tube 10 in a manner that flows in the same direction as the furnace air, and further passes through the core tube 14 and is sent from the outlet section 8 to the rear of the line via the delivery roll 25.

炉気の消費や電力の消費を節減し得る。 Thus, the thin plate A is appropriately preheated while being vertically fed through the feeding cylinder 4, and then heated to a predetermined temperature by the heater 12 on its outer periphery while passing through the reversing roll 3 and the furnace core tube 10. . Next, the core tube 14 is cooled. At this time, a gas circulation type cooling device 6 is connected to the outer periphery of the core tube 14, and the blower 22 blows the furnace air in the core tube into the intake chambers 17, 17.
After being cooled by the water-cooled heat exchanger 21, it is press-fitted into the pressure equalization chambers 16, 16,
Here, the cooling gas with equalized pressure is transferred to the air supply chamber 1.
It becomes a jet flow through the small holes 18 of 5 and 15,
The spray is applied evenly from both sides of the thin plate A in the thickness direction.
Then, the furnace air whose temperature has increased by exchanging heat with the thin plate A is sucked into the intake chambers 17 on both sides of the thin plate in the width direction, and a circulation operation is repeated. Therefore, cooling is completed in a short time, the cooling zone becomes more compact, and since the furnace air is circulated and used as a cooling medium, consumption of furnace air gas is reduced compared to the rigid structure. Moreover, since the furnace air is blown evenly from both sides in the thickness direction of the thin plate and forcibly exhausted from both sides in the width direction, this zone works to maintain the hollow shape of the thin plate and prevent uneven cooling. It is possible to correctly guide the sheet through the tube 10 and provide a favorable uniform heating. As a result, it becomes possible to reduce the cross-sectional area of the furnace core tube 10, and the consumption of furnace air and power can be reduced accordingly.

保持することができる。 However, during operation as described above, the temperature conditions are different between the feed tube 4 and the heating furnace 5, and if left as is, there will be a difference in height between the inlet section 7 and the outlet section 8, which will cause a pressure difference in the internal furnace air. appears, and the prescribed distribution and flow rate of the reactor air is no longer being discharged. However, in the present invention, the gas circulation type cooling device 6 is connected to the inlet tube 4 located nearby by connecting members 33, 33, and the inlet tube 4 is provided with a bellows 9. Therefore, the inlet tube 4 automatically moves up and down via the bellows 9 without having to adjust the height of the inlet and outlet depending on the furnace temperature at the start of operation and during operation. can be maintained at the same level, ie, under the same pressure conditions, at all times.

Since the rolls are fed in a hollow form except for those in contact with the thin plate A, there is no risk of damage caused by dripping during heating or contact with other objects, and each of the rolls that contact the thin plate A is equipped with foreign matter suction means 26, 27, and 28. has been
Dust etc. adhering to the thin plate A during transfer are immediately removed, and the thin plate A is run in a clean state before being sent to the feed tube 4, heating furnace 5 and transfer line, so that good heat treatment can be performed without causing scratches. .
